The in-situ probes of the Aello 1500 series are sensors for the characterization of liquid, disperse and high concentrated systems. The experience of many years research and development of optical sensors resulted in this device group of very com-pact in-situ probes.

The Aello 1560 probe utilizes the spectral extinc-tion of light as measuring principle. Thus this type of sensor is particular suitable for in-line process monitoring and control of complex and high con-centrated multi-phase systems. The system en-ables to measure the size and concentration of submicron dispersions. This is especially important for quality control in polishing processes. The de-sign of the Aello1500 series considers an easy cleanability. An integrated evaluation unit and a direct connectivity to an external PC interface minimize the hardware requirements.

• size: ~ 90 nm .. 1,6 µm*
• concentration: ~ 0.05 .. 15 -%*

* The respective measuring range of the Aello measurement systems depends on the respective particle system (size, opti-cal properties, refraction index etc.)! These properties need to be defined prior measurements
